IIT Bombay....
Its comin closer.. ma days left here are few..
clock is running fast.. and me.. goin into past..
Lookin back..sweet memories.. memories of lifetime...
A journey, wish shall never end...
A life which is to end
only when i am no more
a life which transfered me
in fighter to the core
a season of love and friendship
for eternity which will last
in my future to follow
i will long to relive this past
memories of this part of journey
i'll carry all life along
memories of those precious moments
which made my life a beautiful song
my eyes go teary
emotions fill my heart
as my days left here are few
no it's time to bid adieu
Program in C for False position method...
Important notes:
1. while running the program replace [] (in #include )by less than and greater than symbol since i cant publish post with those symbol.
2. if there is written like less than then use symbol in actual program.

Program in C for Gause Seidel method...
Though I am not smart programmer but still here is code in C for Gause Seidel method...
Important notes:
1. while running the program replace [] (in #include )by less than and greater than symbol since i cant publish post with those symbol.
2. if there is written like less than then use symbol in actual program.
